Definitions

the invention relates to a damper drive device for pivoting an air damper of a ventilation system, in particular a motor vehicle ventilation system, about a pivot axis, with an electric motor for pivoting the air damper drives an output shaft.
FIG. 1 shows an example of the generic air flap drive devices, as they currently, for example, to regulate the fresh air or Recirculating air quantity can be used in automotive ventilation systems.
the damper drive device comprises 100 an electric motor 116 with an internal (not shown) transmission, for pivoting an air damper 112 about a pivot axis 114 drives an output shaft 118.
the electric motor 116 or the internal transmission associated therewith In terms of its strength, it is only able to force up to one certain size.
the engine hub or the output shaft 118 directly to the fulcrum or the pivot axis 114 of the damper 112, wherein it is in this Air damper 112 is an off-center mounted "angle flap", that is the pivot point or the pivot axis 114 is not in the center of gravity the air damper 112.
the invention is based on the object, the generic air damper drive devices to improve such that the above-explained Problems are eliminated or at least reduced.
the air damper drive device is based on the generic State of the art in that a damping device for Damping is provided by applied to the damper torque.
a damping device for Damping is provided by applied to the damper torque.
inventively provided damping device are the on the air damper or the electric motor exerted large Torques so dampened that damage to the electric motor and or a possibly assigned thereto internal transmission avoided becomes.
This solution is, but is not limited to, especially one direct connection of engine hub or output shaft and air damper advantageous. This applies even more if the air damper is stored off-center is, that is, if the pivot axis of the damper does not through their Focus extends.
the damping device is a coupling element and a damping element, wherein the coupling element both is coupled to the output shaft as well as to the damping element.
the Coupling element can be placed, for example, on the output shaft and / or attached to the air damper.
a damping element can be any The damping element known to the person skilled in the art can be used, for example a linear damping element or a rotary damping element.
the coupling element and the Damping element are coupled such that small movements of the output shaft be translated into larger movements by the damping element be steamed.
the damping element a silicone oil damping element is.
silicone oil rotational damping elements are used into consideration.
the coupling element a includes toothed segment coupled to the output shaft.
the damping element a includes gear in which engages the toothed segment.
the invention makes it possible to damage one as a complete module supplied servomotor with internal gear to avoid by caused by vibrations and so on acting on the damper Torques are damped.
FIG 2 is a generally designated 10 air damper drive device shown, which is intended to an air damper 12 about a pivot axis 14 to pivot.
the damper drive device 10 includes an electric motor 16, to be associated with an unspecified internal gear can. About the electric motor 16, an output shaft 18 is driven, the on the pivot axis 14 of the damper 12 is located.
the air damper 12 is itself to an eccentrically mounted angle flap, by their own weight in particular in case of shocks high torques 24 caused become.
a damping device 20, 22 is provided in the illustrated case comprises a coupling element 20 and a damping element 22.
the coupling element 20 has a toothed segment 26 and is on the air flap 12th attached.
the damping element 22 is by a silicone oil rotational damping element realized that has a gear 28, in which the toothed segment 26 engages.
the damping element 22nd via the coupling element 20 additionally driven by the electric motor 16, so that the large occurring torques 24 are damped. It takes over the sector gear 26, the translation of the small engine game in a larger Movement, which is then damped by the damping element 22.
